TLDR
A significant difference was found within the ACL reconstructed group and between the reconstructed and the contralateral intact leg, suggesting ACL reconstruction may not restore tibial rotation even though anterior tibials translation has been reestablished.Abstract:
Recent in vitro research suggests that ACL reconstruction does not restore tibial rotation. This study investigated rotational knee joint stability in vivo during a combined descending and pivoting movement that applies a high rotational load to the knee joint. We studied 20 ACL reconstructed patients (bone–patellar tendon–bone graft) and 15 matched controls with a six-camera optoelectronic system performing the examined movement. In the control group the results showed no significant differences in the amount of tibial rotation between the two sides. No significant differences were also found between the contralateral intact leg of the ACL group and the healthy control. However, a significant difference was found within the ACL reconstructed group and between the reconstructed and the contralateral intact leg. Therefore ACL reconstruction may not restore tibial rotation even though anterior tibial translation has been reestablished.read more

Effect of skin movement artifact on knee kinematics during gait and cutting motions measured in vivo.

TL;DR: Although skin-marker derived kinematics could provide repeatable results this was not representative of the motion of the underlying bones and a standard error of measurement is proposed for the reporting of 3D knee joint kinematic.

Double-bundle ACL reconstruction can improve rotational stability.
TL;DR: Using the new measurement system, patients with double-bundle ACL reconstruction showed better pivot shift control of complex instability than patients with anteromedial and posterolateral single-b Bundle reconstruction.

Tunnel Positioning of Anteromedial and Posterolateral Bundles in Anatomic Anterior Cruciate Ligament Reconstruction: Anatomic and Radiographic Findings
TL;DR: The center of the femoral posterolateral PL bundle is shallow and inferior to the AM bundle, and lies anterior when compared with the typical single-bundle ACL tunnel that reflects the PL bundle.

Anterior cruciate ligament anatomy and function relating to anatomical reconstruction.
TL;DR: This review focuses on the structural as well as the mechanical properties of the ACL and the anatomical details of the femoral origin, midsubstance, and tibial insertion of AM and PL bundles of the ACL.

Prospective Clinical Comparisons of Anatomic Double-Bundle Versus Single-Bundle Anterior Cruciate Ligament Reconstruction Procedures in 328 Consecutive Patients
TL;DR: The anatomic double-bundle procedure may be significantly better concerning the anterior laxity and the pivot shift test than the single-branch procedure, while there may be no significant differences in the other clinical evaluations and the intraoperative and postoperative complications between the two procedures as mentioned in this paper.

TL;DR: A new activity grading scale, where work and sport activities were graded numerically, was constructed as complement to the functional score, showing that the symptom-related score gave a more differentiated picture of the disability.

The effect of medial meniscectomy on anterior-posterior motion of the knee.
TL;DR: In vitro knee-testing apparatus was used to measure anterior-posterior displacement of the tibia on the femur and the accompanying tibial rotation in response to an applied anterior-Posterior force and the coupled internal rotation associated with anterior displacement was lost after section of the anterior cruciate ligament.

TL;DR: The experimental problems related to the reconstruction of the position and orientation of the lower limb bones in space during the execution of locomotion and physical exercises and inaccuracies associated with the relative movement between markers and underlying bone are analysed.
